ASME B18.31.2 ASTM A193 Grade B7 Threaded Rod
ASTM A193 Grade B7 Threaded Rod is a kind of high strength and heat resistant threaded rod manufactured from 4140/4142 quenched and tempered alloy steel for high temperature or high pressure service, used by the plumbing and contracting trade in maintenance departments to secure pressure tanks, valves, and flanges. astm A193 B7 Threaded Rod we produce is fully threaded stud bolts used for High Strength Steel Bolts such as marine anchor bolt, mine steel anchor bolt, wind turbine anchor bolt.
ASTM A193 Grade B7 Threaded Rod we produce is manufactured with rolled threads instead of cut, free from tears or tool marks typically found in cut threads. So the Threaded Rods are smoother and have less surface imperfections that may cause possible failure in severe service applications.
B7 threaded rod is the most economical and most common form of threaded rod and in high demand because of its high strength, excellent heat resistance and resistance to corrosion.
